[0041] The fixing block 161 is fixed on the top surface of the base 110. A horizontally penetrating guide hole is provided on the fixing block 161, and a movable hole communicating with the guide hole is provided on the fixing block 161 in the vertical direction;

[0042] The guide rail block 165 is inserted into the guide hole of the fixing block 161, and the top surface of the guide rail block 165 is inclined;

[0043] The jacking and positioning block 162 is installed in the movable hole of the fixing block 161, and its bottom surface is placed on the top inclined surface of the guide rail block 165;

[0044] The fixing seat 163 is fixed on the top surface of the base 110 and is arranged near the guide hole of the fixing block 161;

[0045] The adjusting bolt 164 is penetrated and screwed on the fixing seat 163, and the tail of the adjusting bolt 164 is rotatably connected to the end of the guide rail block 165.

[0046] Specifically, an installation groove is provided at the end of the guide rail block 165. The tail of the adjusting bolt 164 is inserted into the installation groove. A baffle is provided at the notch position of the installation groove to prevent the tail of the adjusting bolt 164 from detaching from the installation groove.

[0047] In this embodiment, the height of one side of the top inclined surface of the guide rail block 165 close to the circular boss 130 is lower than the height of the side far from the circular boss 130; when the guide rail block 165 moves horizontally, the jacking and positioning block 162 can be jacked up or dropped by means of the top inclined surface of the guide rail block 165.

[0048] In this embodiment, the top surface of the fixing block 161 is inclined, and the inclination angle of the top inclined surface of the fixing block 161 is the same as the inclination angle of the top inclined surface of the guide rail block 165.

[0049] In this embodiment, a dialing block 151 is provided on the top surface of the base 110 near the jacking and positioning mechanism. The dialing block 151 is connected through a driving mechanism 152, and the driving mechanism 152 can drive the dialing block 151 to rotate;

[0050] The driving mechanism 152 is selected from an oil cylinder or a motor; wherein, when the driving mechanism 152 drives the dialing block 151 to rotate, the dialing block 151 can be rotated to the outside of the flange 200a of the large port 220, which is convenient for better clamping and positioning the automotive exhaust end cone 200.

[0051] The usage method of an automatic tooling fixture for a machining center provided by an embodiment of the present utility model is as follows:

[0052] 1. Figures 6-7 As shown, the worker places the exhaust end cone 200 of the vehicle on the lifting and positioning block 162 of the lifting and positioning mechanism, and inserts the small port 230 of the exhaust end cone 200 of the vehicle onto the circular boss 130 for preliminary positioning;

[0053] 2. Adjust the position of the pressing block 140 so that the clamping groove 141 of the pressing block 140 is stuck outside the flange 200a of the small port 230, and adjust the tightness of the bolt connection between the pressing block 140 and the side plate 120 so that the pressing block 140 is clamped outside the flange 200a of the small port 230;

[0054] 3. Rotate the adjusting bolt 164 to drive the guide rail block 165 to move closer to the circular boss 130. During the movement of the guide rail block 165, the top inclined surface of the guide rail block 165 jacks up the lifting and positioning block 162, prompting the lifting and positioning block 162 to clamp the large port 220 to complete the clamping and positioning operation of the exhaust end cone 200 of the vehicle;

[0055] 4. After the processing operation of the taper pipe 210 is completed, rotate the adjusting bolt 164 in the reverse direction to release the clamping and positioning operation of the exhaust end cone 200 of the vehicle.

[0056] It should be noted that in this embodiment, air holes 131 are axially arranged on the circular boss 130, and the other side of the air holes 131 is connected to the airtightness detector 162 through an air pipe 161; after the exhaust end cone 200 of the vehicle is assembled on the fixture, the side surface of the flange 200a on the large port 220 is attached to the air holes 131.

[0057] When verifying whether the fixture is clamped, gas is introduced through the air holes 131. When the airtightness detector reaches the standard value, the gas source is cut off to ensure a constant air pressure inside the air holes 131 for a certain period of time; after the air pressure is stable, the detection link is entered. The pressure sensor of the airtightness detector records the current pressure value in real time. After testing for a certain period of time, the pressure difference between the real-time pressure value of the air holes 131 and the standard value is compared to determine whether there is gas leakage and whether the workpiece is clamped.

When it is necessary to process the taper pipe of the exhaust end cone of the vehicle with the aid of a machining center, the exhaust end cone of the vehicle can be clamped and fixed in advance, and the operation is convenient.
